release(v2.0.3): fix Directory tab managed-filter bug and site-status 500 (#186)

- GET /api/directory-admin/resources let every kind:'host' resource through
  regardless of promotion status, so "Auto-promote to Directory" unchecked on
  a discovery plugin never kept unpromoted devices out of the Directory tab.
- GET /api/directory-admin/site-status queried the nonexistent Resource.subType
  column instead of metadata.subType, throwing SequelizeDatabaseError.
- Added a "Show ignored" toggle to Discovered Inventory (off by default).
- Untracked nodejs/config/inventory.sqlite -- the app's default runtime DB,
  not a fixture, committed by mistake across 13 prior releases.
